Frequently asked questions
How the maths works
A student loan is a fixed-rate amortizing loan. A grace period lets interest accumulate and capitalize before payments start, so the balance you repay can exceed what you borrowed.
- 1During the grace period, monthly interest accrues on the balance and is capitalized (added to principal) when repayment begins.
- 2Base payment M = L·r / (1 − (1+r)^−n), where L is the capitalized balance, r the monthly rate and n the term in months.
- 3Each month, interest = balance·r and the rest of the payment reduces principal.
- 4An extra monthly payment goes 100% to principal, shortening the term and cutting total interest.
Figures are illustrative and exclude fees, deferment and forgiveness programs. Not financial advice.
Everything you need to know
What is interest capitalization?
During a grace period (typically six months after graduation), no payments are due but interest keeps accruing on unsubsidized loans.
When repayment starts, that accrued interest is added to your principal — you then pay interest on interest, which is why the balance can grow before you make a single payment.
Extra payments are the fastest lever
Every extra dollar you pay goes straight to principal, which cuts future interest and shortens the term — often by years.
The calculator shows exactly how many months (and how much interest) an extra monthly payment saves on your specific loan.
